Common Dreams collects stories indicate the covert drone campaign in Yemen is fuelling radicalization. According to the Washington Post story cited, “In 2009, when President Obama was first known to have authorized a missile strike on Yemen, U.S. officials said there were no more than 300 core AQAP members. That number has grown in recent years to 700 or more, Yemeni officials and tribal leaders say. In addition, hundreds of tribesmen have joined AQAP in the fight against the U.S.-backed Yemeni government”.
